The present invention provides an integrated high voltage capacitor, a
method of manufacture therefore, and an integrated circuit chip including
the same. The integrated high voltage capacitor, among other features,
includes a first capacitor plate (120) located over or in a semiconductor
substrate (105), and an insulator (130) located over the first capacitor
plate (120), at least a portion of the insulator (130) comprising an
interlevel dielectric layer (135, 138, 143, or 148). The integrated high
voltage capacitor further includes capacitance uniformity structures
(910) located at least partially within the insulator (130) and a second
capacitor plate (160) located over the insulator (130).
